Adjustment of the cantilever resona
fr equency, voltage, and reference value are set automatically.
Considerations in using t
• Excitation voltage to be applied to the cantilever
In this system t
cantilever to "high" or "low". When "high" is selected, up to 1
cantilever. Use this "high" setting for in-liquid observation, or when a cantilever in
use does not easily resonate. On the other hand, if, in observing a sp
vacuum, you set the voltage to "high," the cantilever might break. To avoid this, you
should use the "low" setting.
• Usable cantilever resonance frequency
The range of cantilever resonance frequencies that can be adjusted by using the
tuning function is 1 kHz to 1 MHz.
• If tuning fails
If the message "Auto Tune Failed" is displayed, carry out the operations described in
Sect. 5.4.1, "Checking before approach" and in Sect. ５ .4.1, "Adjusting the
photodiode position." If the "Auto Tune Failed" message still does not disappear,
adjust the resonance frequency manually, referring to Sect. 5.10.3,"■ Cantilever."
Tuning
Adjust the cantilever resonance point using the Cantilever Autotune Setup dialo
opened by clicking on Cantilever Autotune Setup in the SPM Scan pull-down menu.
For further details, refer to Section 5.10.1, "SPM Scan Menu."
